I do not agree that the MBP 2016 was a statement about forgetting the pro user. The lack of upgrades to the Mac Pro was and also that we did not get an Apple design external monitor. The MBP 2016 is good for pros where the performance is adequate, which (of course) it will not be for all. As a photographer using mostly 50MP files from the Canon 5DSR the speed when using the LG 5K display is fine for my purpose in the sense that I'm hardly ever waiting for the machine to respond. I can keep a fluid editing workflow with this machine. If I was editing 100MP files from the Phase One camera I might have a different opinion
Yes the machine it is ok for some Pros... but for me that was not exactly the issue. The issue was that you created an event called "Back to the Mac" (I think that was the titlle or something like that), you just release a laptop, with some handicaps for some Pro users (just 16GB of RAM, not the best option in mobile GPU, and nice price increase thanks to the touchbar...) and that it is... forget about the rest of the lines in the Mac: iMac, Mac Mini and Mac Pro (this two last with very long overdue updates). Then you are also in the last years dropping support on your Pro apps, like realesing Final Cut X that, if you read many video forums, make a lot of people to move from Final Cut 7 to other programs, dropping Aperture... etc... Pro people was worried... and what it is more problematic for Apple, nowadays there is little need to stay in that platform, unless you are using Final Cut X, Logic Pro or developing apps for iOS with XCode, the rest of programs that you are probably use (Adobe Cloud Suite, Lightroom, Capture One, ... ) have a version for Windows.
So, for me this event it is for all those Pros that maybe were thinking move to Windows... telling them, it is ok, we are not forgetting you.
